Improvement in paper-cutting- machines



HENRY A. GAGE. 0E MANCHESTER, NEW HAMPSHIRE 13mm Patent No. A100,391, dated March. 1, 1870.

mpnvrnvmrr nr PAPER-CUTTING MACHINES.

` The Schedule referred to in these Lettere` Patent and ma-king part of the same.

` i '.l'o all lwhom 'it may concern l u y Be it known` that I, HENRY A. GAGE, ofManchester, Hillsborough county, in the State 'of New Hampshire, have invented certain new and useful Imi provements in Paper-Cutting Machines and I hereby declare the following to be a full and exact description 4 l thereof, reference being had to the accompanying drawings forming part of this specification. p

`The nature or essenceof myvinvention consists in giving the cutting knife a drawing cut, by means of the `inclined dovet-ailed. ribs on the plate that carries the y knife, working in inclined dovetailed scores in the stationary or ciampi-ng plate, by` means of an inclined screw arranged parallel yto .the inclined ribs on 'and i scores in the plates above mentioned.- r

`Figure lis aplan` ortop view of a paper-cntting machine with my improvements.

Figure 2 is an elevation ofthe rear ofthe machine.

Figure 3 is an elevation of the front of th machine. Y In the accompanying drawlngsi 1 r A is the table or base of the presspart of the cut.-

` ting machine.

B is'the clamping plate, which may be made of castiron in the form shown, and perforated for the screws C G which work in female screws" `in the perforations to press the papelito be out on the base, and hold it while it is being cut, and then release it so that it may be taken away. i y

Thebase .A is perforatedfor the screws C G, which are made smaller where they pass through the base,

so as to form a shoulderon thescrews and make them n lift theclamping plate, andthe lower ends of the screws are provided with` nuts, as shown by' dotted lines in tig. 2, so arranged that the screws turn freely in the base A without traversing when they are turned to raise `o r lower the clamping plate B.

been cut.

The clamping plate B, or the perpendicular part ofV it, is provided with two `inclined dovetaiied scores D D to receive the dovetailed inclined'ribs E E on the plate F that carriesthe knife G to cut the paper H on the base A clamped by the plate B.

The ribs E E are fitted to work freely in the scores D D to guide the plate -F andknife Gso that it will cut the paper H with a drawing cut or stroke, according to the inclination of theribs and grooves.

l The knife Ginay be fastened to the plate Fby screws or rivets.

To traverse the knife and cut the paper, I make a..

protuberance, I, on the plate B to extend over the knife-plate F, and make a female screw in the protuberance for the screw J to work in, which screw is in- -clined to coi-respond or be parallel with the scores and ribs, and the lower end of the screw ste-ps in a protuberance, K, on the plate F, and the lower endof the screw J has .a groove around it for the shaft of the' screw L in the protuberance K, so that the screw will draw np the plate F and knife G after the paper has To turn the screw J, I fasten the hand-wheel M upon its npper end with a crank-pin, N, in it, so that it maybe turned with'facility.

Having described my improvements in paper-cut ting machines,

i I claim- `Workingthe knife G and plate Fyby an inclined screw arranged parallel to the inclined ribs E and scores Din a protuberance on the clamping plate of the machine.
